Today we encountered a situation where a Proxmox system’s KVM virtual machine refused to delete after the storage volume that it’s virtual HDD resided on was lost; trying to delete the KVM from the web GUI resulted in the following error:
TASK ERROR: storage ‘proxmoxHDD’ does not exists
Attempting to delete it from the command line using:
qm destroy [VM ID]
storage ‘proxmoxHDD’ does not exists
Fortunately, there’s a way around this. The KVM config files live in:
Move or erase the [VM ID].conf file and when you refresh your web GUI the VM should be gone.
